/**
 * Widget that places a powered-by-Juneau message on the page.
 * 
 * <p>
 * The variable it resolves is <js>"$W{PoweredByJuneau}"</js>.
 * 
 * <p>
 * It produces a simple Apache Juneau icon floating on the right.
 * Typically it's used in the footer of the page, as shown below in the <code>AddressBookResource</code> from the examples:
 * 
 * <p class='bcode'>
 * 	<ja>@RestResource</ja>(
 * 		path=<js>"/addressBook"</js>,
 * 		widgets={
 * 			PoweredByJuneau.<jk>class</jk>
 * 		},
 * 		htmldoc=<ja>@HtmlDoc</ja>(
 * 			footer=<js>"$W{PoweredByJuneau}"</js>
 * 		)
 * </p>
 * 
 * <p>
 * It renders the following image:
 * <img class='bordered' src='doc-files/PoweredByJuneauWidget.png'>
 * 
 * <h5 class='section'>See Also:</h5>
 * <ul>
 * 	<li class='link'><a class="doclink" href="../../../../../overview-summary.html#juneau-rest-server.Widgets">Overview &gt; juneau-rest-server &gt; Widgets</a>
